Communication method, and electronic device therefor

1. A communication method for performing communication between more than two parties, using an electronic device, the communication method comprising: receiving, by the electronic device, an audio signal of a transmitter; detecting, by the electronic device, sensitive information in the audio signal based on a context of another audio signal in a communication history of the transmitter; determining, by the electronic device, a receiver to receive the audio signal; encrypting, by the electronic device, the sensitive information by using characteristic information of the determined receiver; and transmitting, by the electronic device, the audio signal including the encrypted sensitive information.

2. The communication method of claim 1 , wherein the content of the audio signal is a meaning of the audio signal or an audio characteristic of the audio signal.

3. The communication method of claim 1 , wherein the content of the audio signal is a meaning of the audio signal, and detecting the sensitive information based on the meaning of the audio signal comprises detecting the sensitive information based on whether the audio signal of the transmitter comprises a predetermined important keyword or a predetermined important keyword type.

4. The communication method of claim 1 , wherein the receiver is determined based on a name of the receiver detected in the audio signal, or the context of the other audio signal in the communication history of the transmitter.

5. The communication method of claim 1 , wherein the characteristic information of the receiver comprises at least one of voiceprint information, fingerprint information, face information, vein pattern information, palm print information, and iris information of the receiver.

6. A communication method for performing communication between more than two parties, using an electronic device, the communication method comprising: receiving, by the electronic device, an audio signal comprising sensitive information that is detected based on a context of another audio signal in a communication history of a transmitter, and is encrypted by using characteristic information of a receiver, wherein the receiver is determined by the transmitter to receive the audio signal; acquiring, by the electronic device, the characteristic information of the receiver; and decrypting, by the electronic device, the encrypted sensitive information by using the characteristic information of the receiver.

7. The communication method of claim 6 , wherein the content of the audio signal is a meaning of the audio signal or an audio characteristic of the audio signal of the transmitter.

8. The communication method of claim 6 , wherein the characteristic information comprises at least one of voiceprint information, fingerprint information, face information, vein pattern information, palm print information, and iris information of the receiver, and acquiring the voiceprint information comprises: detecting a respiratory signal from the receiver; and determining, based on the respiratory signal, whether the voiceprint information is generated from the receiver.

9. An electronic device for performing communication between more than two parties comprising at least one processor configured to: receive an audio signal of a transmitter; detect sensitive information in the audio signal based on a context of another audio signal in a communication history of the transmitter; determine a receiver to receive the audio signal, encrypt the sensitive information by using characteristic information of the determined receiver; and transmit the audio signal including the encrypted sensitive information.

10. The electronic device of claim 9 , wherein the content of the audio signal is a meaning of the audio signal or an audio characteristic of the audio signal.

11. The electronic device of claim 9 , wherein the at least one processor is further configured to determine the receiver of the audio signal based on a name of the receiver detected in the audio signal, or the context of the other audio signal in the communication history of the transmitter.

12. An electronic device for performing communication between more than two parties comprising at least one processor configured to: receive an audio signal comprising sensitive information that is detected based on a context of another audio signal in a communication history of a transmitter, and is encrypted by using characteristic information of a receiver, wherein the receiver is determined by the transmitter to receive the audio signal; acquire the characteristic information of the receiver; and decrypt the encrypted audio signal by using the characteristic information of the receiver.

13. The electronic device of claim 12 , wherein the content of the audio signal is a meaning of the audio signal or an audio characteristic of the audio signal.

14. The electronic device of claim 12 , wherein the characteristic information comprises at least one of voiceprint information, fingerprint information, face information, vein pattern information, palm print information, and iris information of the receiver, and the at least one processor is further configured to detect a respiratory signal from the receiver when the voiceprint information is acquired, and determine, based on the detected respiratory signal, whether the voiceprint information is generated from the receiver.

15. A computer program product comprising a non-transitory computer-readable storage medium having a computer-readable program stored therein, wherein the computer-readable program, when executed on a computing device, causes the computing device to: receive an audio signal of a transmitter; detect sensitive information in the audio signal based on a context of another audio signal in a communication history of the transmitter; determine a receiver to receive the audio signal; encrypt the sensitive information by using characteristic information of the determined receiver; and transmit the audio signal including the encrypted sensitive information.
